Xfinity Now not working on xfinity.com

  Deeply request.Xfinity now services\Accounts, be somehow linked to xfinity.com. As i would login to xfinity.com go to payment methods everything would load before.I was able to change anything, page would load again and say xfinity account does not exist..

   I Don't want to pay more, just to be able to talk to an actual person, who could actually potentially help me, artificial intelligence not helpful in this scenario!
